Small Cover Area and High Efficiency Silica Sand Drum Dryer

High efficiency sand dryer/silica sand dryer machine/quartz sand dryer machine with best quality

sand dryer is our major product, with professional technology support and all-around service.

sand dryer is handling by bringing it into direct contact with a heated gas.Dryer machine is made up of a large rotating cylindrical tube, the rotary dryer slopes slightly so that the discharge of the dryer's outlet is lower than the material inlet in order to convey the material through the rotary dryer under.

Working principle of sand dryer:

Material to be dried enters the dryer and as the dryer machine rotates, the material is lifted up by a series of internal fins lining of the wall on the rotary dryer, when the sand raising up by the lifting board,and will falls back down to the bottom of the rotary dryer, passing through the hot gas stream when the sand falling.

The sand and the hot air into the sand dryer with same direction(known as co-current flow) or different direction(known as counter-current flow) .

The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the rotary dryer is called a direct heated rotary dryer, alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated, when the gas stream is preheated by some means where burner combustion gases do not enter the rotary dryer, the rotary dryer known as an indirect-heated type, often, indirect heated rotary dryers are used when product contamination is concern.
